Seal failure will occur if the following operating conditions are introduced into the hydraulic system. a) A higher pressure is applied to the tank/return port than at the service port b) A higher pressure is applied to service port than at the pressure port. c) Depressurisation of the hydraulic supply pressure with the valve in a pressure to service flow mode. (If this is a system design requirement we recommend the 5101 or 8001 valve types are used). d) Back pressure at the tank port exceeding the maximum recommended 200 psi (14 bar) above the service line pressure. If conditions (c) and (d) can arise during normal operation we recommend the following action is taken. To eliminate condition (c) install a check valve directly at pressure P inlet port. To eliminate condition (d) install a check valve directly at the tank T port. sales@bifold-fluidpower.co.uk 8

9 eliability and Innovation in directional control valves e) Valve types 5101, 5102, 8001 and 8002 are fitted with a bi-directional seal which is capable of tolerating flow from the pressure (P) port to the service (S) port and vice versa. The reverse flow capability of these valves is only permitted while the valve is in a static mode i.e. the valve must not change position whilst in a reverse flow mode as the seal will be damaged. Note: Condition (d) will remain applicable to these valve types. TESTING For the purpose of proof testing an entire hydraulic system, including return/tank lines at the maximum test pressure, the tank port lines can be pressurised providing an equivalent pressure is always maintained at the valve pressure port with the valve in a pressure to service mode. Always dissipate a test pressure down stream of the tank port. Under no circumstances should the tank port be plugged. To depressurise a control circuit with the direction for flow maintained P to S (Normally Open Valve or Normally Closed Valve pilot operated to open), pressure must always be dissipated down stream of the service port. (Excluding valves with reverse flow capability, refer to warning paragraph (e)). Other Slide Valve Types Effected (i) 3-way and 4-way for gas service Types: 5500, 8400 and 8408 (ii) 2-way, 2 position valves for gas service Types: 5502 and 8402 (iii)2-way, 2 position valves for hydraulic service Types 8102 and 8112 The above valve types are fitted with a bi-directional seal which is capable of tolerating flow from the pressure (P) port to the service port (S) and vice versa. The reverse flow capability of these valves is only permitted while the valve is in a static mode i.e. the valve must not change position whilst in a reverse flow mode as the seal will be damaged. (efer to warning paragraph (e)) NOTE To eliminate the modes of failure as described (excludes reverse flow type, refer to warning), we offer a stackable valve system, incorporating 5100 series, subbase manifolds, thermal relief and check valves. We also manufacture a range of block before bleed and balanced poppet valves which are not susceptible to the seal damage through reverse flow mode applications. For further details on these and our stackable valve system please contact Fluidpower. sales@bifold-fluidpower.co.uk 9
